HERBERT CHRISTOPHER HEATH, OF VEMBLEY, EUGENE DAVID REGIS, OF STONE- BRIDGE PARK, AND HAROLD GEORGE RUDDICK, OF ACTOS, ENGLAND, ASSIGNORS TO GENERAL ELECTRIC COMPANY, A CORPORATION OF N'EVJ YORK.

ELECTRI Application filed December 26, 1925, Serial No to switch installations in which an elevated platform is arranged adjacent the switches for supporting apparatus such as isolating switches, switch operating mechanism, and the bus bar system which is associated with the switches. In accordance with our invention the supporting base for the switches comprises the receptacle for receiving the expelled gases and the pillars by which the platform is supported serve to convey the gases from the switches to the base.

Our invention will be better understood from the following description taken in connection with the accompanying drawing, and its scope will be pointed out in the appended claims.

In the drawing, Figure 1 is a front elevation partly in section of a portion of a switch installation embodying our invention; and Figure 2 is a partial side view of the same also partly in section.

Referring to the drawing we have shown three switches 11 mounted upon a common bed plate 12 which is raised above the floor or ground 13 by supports 14.. The isolating switch chambers 15 and the bus bar chambers 16 are carried by the horizontal frame 17 comprising an elevated platform and this frame is supported upon vertical hollow pillars 18 resting on the bed plate 12. It ls to be understood of course that switches 11, the isolating switch chambers and the bus bar chambers may be of any desired type, the drawing in this case being merely illustrative of one form or type.

Each pillar 18 is connected at its upper end by a pipe 2O with the interior of one of the switches 11. The space below the two right hand pillars 18 with which these pillars communicate is shown filled with a loose gas-cooling material 19 which for example may be gravel. If desired the gas-cooling material may be used only in the pillars as C SWITCH.

. 77,754, and in Great Britain January 15, 1925.

shown in the left hand pillar 18 or if desired the gas-cooling material may be used in both the base and the pillars.

Ilich the switches operate to open the circuit controlled thereby the hot gases escape through the pipes 20 into the pillars 18. IlVhei-e the pillars are open, such as the two right hand pillars illustrated, the gases begin to expand and cool in the pillars but are more `fully expanded and cooled in the space below, which is filled with the cooling material.

lVhen two or more switch installations are arranged in proximity or in line the supports 14 may be provided with openings 21 to establish communication between adjacent base plates.

The switches may be provided with tops 22 carrying the terminals, which when the switch is to be removed may be lifted up to a position such as shown in dotted lines at 28, thus breaking connection with the pipe 2O at the place marked 24C. If the switch is to be removed horizontally it is preferably severed from the supporting pillar at the place marked 25 which for this purpose should be a detachable joint.

1What we claim as new and desire to secure by Letters Patent of the United States, is

1. In an electric switch installation comprising a fluid break switch, a platform supported thereover and a hollowsupporting pillar for said platform connected to receive gases expelled from the switch.

2. In combination a fluid break switch, auxiliary mechanism arranged thereover, a hollow supporting pillar for said mechanism adjacent said switch and means forming a communicating passage between the switch and the supporting pillar.

3. In combination a fluid break switch, elevated auxiliary mechanism associated therewith, a hollow supporting base for the switch adapted to receive and cool gases ejected therefrom and a hollow supporting pillar for the auxiliary mechanism connected to conduct the eject ad gases from the switch to the base.

el. In combination a plurality of fluid break switches, a platform arranged thereover, hollow supporting pillars for the platform arranged between the switches, and pipe connections between the switches and the pillars whereby the gases discharged from the. switch may be delivered into the pillars.

5. In combination a plurality of fluid- 5 break switches7 a hollow supporting hase therefor containing gas-cooling material, disconnecting switches connected with the switches, a raised platform carrying` said disconnecting switches, and a plurality of 10 hollow pillars for supporting the raised platform, said pillars being connected with the switches and with the hollow base to conduct gases ejected from the switches to the base.

In witness whereof, we have hereunto set 15 our hands this fourteenth day of December,

HERBERT CHRISTOPHER HEATH.
